Why does a Bunsen burner have an air hole?
It's to allow air to mix with the gas before burning - creating a hotter flame.
Explain why opening the air hole of a Bunsen burner makes the flame hotter.?
Because more air is able to fuel the flame's reaction; the collar at the bottom of the tube is adjusted so more air can mix with the gas before combustion, the flame will burn hotter.

Why does flames of acandle rises upward?
Air in a flame is hotter, and therefore less dense. It will "float" in normal (cooler) air.
How you can calculate the heat irradiative by the flame?

Burning to dryness can cause your watch glass to break. Burning all the methanol creates a hotter surface as the flame is trying to burn the dry salts. Blow out the flame before the methanol is completely consumed.
Flame luminosity with the combustion process?
No such thing, a luminous flame is an incomplete burn.
Which is dangerous the yellow flame or the blue flame?
A blue flame is hotter than a yellow flame. First, "...the blue flame..." IS NOT more dangerous than "...the yellow flame." The yellow flame is more dangerous because it is an indicator of IMCOMPLETE COMBUSTION resulting from burning with a shortage of air, and thus not enough oxygen. The reason this is dangerous, actually DEADLY, is that when combustion [burning] occurs in an oxygen deficient atmosphere, one of the major byproducts of that combustion process is CARBON MONOXIDE, a colorless, odorless, and tasteless gas which is toxic and therefore deadly to any creature that breathes air.
What part of a flame burns hotter?
